Data from comm port

[remle]

Can vbscript extract data from a comm port.

I have a device that produces data in an ascii format but I need to access it via the comm port.

Any help would be appreciated.

Thanks

Look in Homeseer help for hs.OpenCommPort. There are related functions that allow reading and writing to the port.

Hi

Thanks for the point in the right direction. I looked at the help file but it is pretty sparce. I could use a code example to get me going.

That is one of my big qualms about the help files in HS. If you know what you are doing they are fine but for a newbie they are a little lacking.

Thanks

Add this to the startup.txt script (in the Homeseer/scripts folder):


'*****Set Com port *****
e=hs.OpenComPort(2,"9600,n,8,1",1,"Mydata.txt","main")
if e<> "" then
hs.writelog "Error opening COM2",e
else
hs.writelog "COM2", "Com port setup complete"
end if

Change the com port number (in red) to the one you are using.

Next, save this script as Mydata.txt and place it in the Homeseer/scripts library:

Sub main(Getdata)
hs.writelog "Comport data",Getdata
end sub

Reboot Homeseer.

Each time data is sent to the com port, you should now see it written in the Homeseer log.

That is exactly the help I needed. I now have my script running the way I wanted.

Thanks very much
